They’ve come, of course they’ve come, because that’s what the NFL people do. They arrive in droves, asking, probing, wanting to know every minute detail about the player and — more importantly — the person.

The NFL coaches and talent evaluators can see the player with their own eyes. The person? Well, that’s more far-reaching. So in the months and weeks before the NFL Draft, college assistant coaches are put on the spot: Do you vouch for your guy, or not?

Taylor Lewan, the player, is an easy one. Tall, statuesque, prototype NFL franchise left tackle, a natural pass protector and with a mean streak on the field that can’t be taught. On Thursday night, Lewan will hear his name called early during the first round of the draft. The team that takes him — if the Giants are lucky, he’ll be sitting there at No. 12, but probably not — will make the selection after vetting Lewan, which means clearing up two recent incidents that could be nothing much to sweat or warning signs that he’s trouble.

“I never had any hesitations recommending him,’’ Darrell Funk, Michigan’s offensive line coach, told The Post on Tuesday. “I’d put my stamp on him every time.’’

Lewan has some marks on his personal résumé that may be red flags for NFL teams. Lewan is expected to be charged May 19 in Ann Arbor with one count of aggravated assault and two counts of assault and battery stemming from an alleged Dec. 1 early-morning altercation with Ohio State fans after the Michigan State-Ohio State game won by the Buckeyes, 42-41. Lewan denies he committed any crime.

That is not the only blemish — or perceived blemish — teams need to illuminate regarding Lewan. His name surfaced earlier this year regarding the investigation of former Michigan kicker Brendan Gibbons for a 2009 sexual assault. There are allegations Lewan attempted to intimidate a woman into not filing charges by threatening to “rape’’ her if she went to the police, a claim Lewan denies.

“I’ve said a lot of dumb things in my life, but those are not things that I said,’’ Lewan said. “I would never disrespect a woman like that. I consider myself a guy who likes to hold doors, not threaten people.”

Funk has heard all about these incidents.

“Those situations there, I couldn’t talk about them if I wanted to,’’ Funk said. “I have no reservations about Taylor Lewan.’’

Do the Giants? There was a time when they would not even consider taking a player they deemed too much of a character risk. Times have changed.

“Back years ago, we used to take players off the board,’’ general manager Jerry Reese said. “We keep players on the board now so we can see them.’’

This does not mean the Giants will take anyone, no matter what. Though Reese says, “We’re going to keep all of our options open … we’ll respect all of the players in the draft,’’ he admits there are some players the Giants won’t touch.

Lewan is rated no lower than the third-best offensive tackle — behind Greg Robinson of Auburn and Jake Matthews of Texas A&M — and he could go as high as No. 6 to the Falcons. If he’s still on the board, the Giants seemingly would gleefully take a 6-foot-7, 309-pound stud who could become their left tackle for a decade as they continue to rebuild their offensive line and try to keep Eli Manning’s 33-year-old body intact.

One scout describes Lewan as having a “quirky personality,’’ and it was not meant as a compliment. For a time, he rode around the Michigan campus on a tandem bicycle. He went through a period when he wore a fedora. He and the other offensive linemen had a pet pig.

But Lewan also spent every Thursday night at C.S. Mott Children’s Hospital in Ann Arbor, visiting with sick kids.

“Those kids [at the hospital] loved him,’’ Funk said. “He gave so much of his time. We have a woman’s football academy that benefits cancer, those women loved being around him when he ran the drills. They love his personality. Our secretaries love him, coaches’ families love him. I like to be around him.’’

There are those who believe the Giants’ offensive line lost too much of its past aggressiveness and nasty temperament. Lewan — who says his goal is to “put the guy in the dirt every single play” — brings both in large measures.

“As football coaches, we work harder to get the guy that’s kind of a passive guy to play with energy and play with passion,’’ Funk said. “It’s a lot easier to tone a guy down a little bit, and we were able to do that with Taylor and still not mess with his aggression. He’s going to be a great asset for whoever picks him.’’
